If you happened to have a GeForce card you probably want to get the most out of it. Debian comes with a NVIDIA open source driver called nouveau. If this is not what you are up to you have a choice to install proprietary nvidia driver from the debian’s non-free repository. Another choice you available to you is to use NVIDIA’s proprietary up to date driver from nvidia.com. The choice is yours, but I would recommend to use debian’s repository to start with. First make sure to add contrib and non-free repositories to your sources.list. Example:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16
First you may want to attempt to detect your NVIDIA card with nvidia-detect command. Install and run nvidia-detect:
1 2 3 4 5 6 7 8
At this stage we are ready to install driver or better “NVIDIA Dynamic Kernel Module Support”:
Once finished you will need to enable your new “nvidia” module with XORG xserver by creating a new xorg.conf configuration file within /etc/X11/ directory. You can do this either manually or use nvidia script to do this job:
1 2 3 4 5 6
All what needs to be done at this point is to reboot your PC as this will blacklist your previous NVIDIA open source driver “nouveau” and initiate your X with new “nvidia” module. All done.
